Hi Nick,
I’ve just had it confirmed. After 3 days the refund will go on a dormant list. When you next touch the card it will resend the refund ready to pick up on the touch after that. This should always work for rail journeys (unless it’s a really short one) and will only fail if the only journey is a singular bus or tram journey. It will keep trying for six months after which you would need to call customer services.
